I am very new at parallax, so please forgive my ignorance.  I purchase the BS2 Homework board few months ago, and learning to program it and use it.
 

I needed more I/0 for my current project and was adviced to use the SX chip added to my BS2.

 

Now as far as I can see, the SX is faster and has less I/O; but cheaper.

 

Why should I use the BS2 instead of few SX chips?

 

What are the major difference between the two microcontroller beside the ones I already mentioned?

 

again, please forgive my ignorance, just looking to learn. and in the process contribute to this great forum.
